Spotted on the entrance, were two camouflaged prototype models. Now, we aren't sure what they are, but it seems to us that the white car upfront, might be the new 2010 Opel Astra. Although it officially debut, but Opel engineers are still developing and improving the chassis before it goes on sale. The other car behind it, we reckon that it might just be the 2011 Buick Excelle, which is Buick's smallest car yet, and will be based on the Chevrolet Cruze.
Got any other suggestions on identifying these cars? Well, post your opinion in the comments.
